Method for characterize security technology deployment telemetry across a computer network

A method includes identifying a first group of objects generated by security tools during a first time interval and containing cotemporal, analogous characteristics identifying a first endpoint device connected to a computer network; based on the first group of objects, confirming detection of the first endpoint device by a first security tool and a second security tool during the first time interval; identifying a second group of objects generated by security tools during a second time interval and containing cotemporal, analogous characteristics identifying the first endpoint device; based on the second group of objects, confirming detection of the first endpoint device by the second security tool during the second time interval; and responsive to absence of detection of the first endpoint device by the first security tool during the second time interval, generating a source remove event specifying removal of the first security tool from the first endpoint device.
